Disk cloner is a device for duplicating or creating a bit-by-bit copy of a hard disk. The current methodology for cloning a large disk is inefficient which results in a very slow speed of such a cloning process. The program called dd is often used for this duplication purpose. The cloning speed depends on both hardware and software. This paper aims to utilize the technique of multi-threading on multi-core...
Healthy living style generates the demand for high quality of food. However, traceability system across the supply chain is still facing many challenges from technical perspectives. This paper aims to study the feasibility of traceability system at the government animal checkpoint and how UHF-radio frequency identification (RFID) technology can be deployed for enabling such system. UHF-RFID technical...
In a radio frequency identification (RFID) system, when more than one tag communicates with a reader at the same time, a collision will occur resulting in the failure of that communication. Many anti-collision algorithms, such as binary tree (BT), FSA, and DFSA have been used in ISO and EPC standards to prevent such a collision. This paper develops a new anti-collision algorithm based on the BT and...
An RFID system consists of an RFID reader, a server connected to a database, and RFID tags attached to the objects needed to be identified. We are interested in the case where two tags are needed to be simultaneously scanned in a readerpsilas field, for which many protocols have been proposed in literature. They however are all insecure for the special case, where an adversary, acting as a reader,...
A collision occurs when more than two tags present in the readerpsilas field of a radio frequency identification system. Anti-collision algorithms such as binary trees and dynamic framed slotted aloha (DFSA) have been employed to prevent such a collision. The identification number of tag consists of 64 bits and certain parts of 64 bits can be considered a priori-information. This paper proposes a...
Sensor is one of the popular devices used in many applications nowadays including the intelligent transportation system (ITS) which is widely utilized in the automatic vehicle identification (AVI) system. In this research, we propose an implementation of photoelectric sensors as a vehicle detection tool in an RFID-based poultry traceability system to detect poultry transport vehicle entering and leaving...
Different types of media such as hard disk, flash drive and memory card require different memory formats. File allocation table (FAT) file system is ideal for use with devices that are optimized for removable media. FAT16 is a common file system for Windows family of operating systems in hard disk and also in removable media. When transferring data from hard disk to other types of media, the memory...
Since the first outbreak of avian flu, the ability to discover the origin of the disease as soon as possible is highly required. To trace back to the origin, it is necessary to identify and verify the source of information. Radio Frequency Identification or RFID is a popular tool to identify animal and automatically collect information for traceability purpose. In this paper, we present a poultry...
When more than two tags respond to a reader request at same time slot, the tag collision occurs. This is one of disadvantages in radio frequency identification (RFID) system. The performance of anti-collision algorithms is important to overcome this problem. In this paper, the performance of dynamic framed slotted ALOHA (DFSA) is studied. The DFSA with mute tags is considered and compared with framed...
Web-service application has become more important for sharing information among organizations. In this paper, we proposed Web-service application for poultry traceability system. The traceability system is required for identification and verification of the products. The system architecture and algorithm are presented in two different models depending on the party who handles the server operation...
Dynamic environments pose a challenge to the read performances of current RFID systems. Moving tags on a conveyor belt affect the read performance of a static reader. This paper attempts to evaluate a static reader identifying moving tags on a conveyor belt. We propose an algorithm enabling the conveyor belt to dynamically adjust its speed for the RFID reader to reliably identify tags without prior...
In a developed country, farmers have an access to advance technology for radio frequency identification (RFID) farm management. Recently, RFID has become a globally recognized technology for animal identification to simplify farm activities such as automatic feeding. In a developing country, Thailand, RFID is a cutting edge technology unknown to most farmers. Uneducated farm labors are often afraid...
